The Design and Implementation of an Accelerometer-Based 3-In-1 Heart Rate, Respiratory Rate, and Body Tilting Angle Sensing Companion Chip

Heart rate, respiratory rate, and the human posture representing by body tilting angle are the three most important indices in human health care. The technologies for the measurement of these three indices are very matured and ready to be used in portable or wearable health care products. However, separated technology has to be used if these three indices have to be measured simultaneously. Hence, the system will have high cost, low portability, and inconvenient and uncomfortable for the users wearing the system. In this proposal, a single sensing technique with a single device on a single location will be developed for the measurement of these three indices. It is the sensing device - accelerometer to be used in this study. In the study, the detection of these three indices will also be fulfilled when the human is in the dynamic status with proper data processing technologies. As the results, the developed single sensing technology can be really applied in the anytime, anywhere, and any movement application scenarios. Furthermore, the developed accelerometer-based 3-in-1 heart rate, respiratory rate, and body tilting angles sensing method will be implemented in hardware as a companion chip. With this chip, it can help to reduce the cost and complexity of health care system design, lower the system power consumption, increase the battery hour, and to increase the portability of the system. With the companion chip to offload the efforts of parameter detection from the system, the micro-controller in the system could have more space and capability for future changes of the system functionality. In this study, an accelerometer-based companion chip will be designed and developed with the capability of detection human heart rate, respiratory rate, and body tilting angles in dynamic activities. It will make the accelerometer-based sensing system on medical care applications more feasible and more convenient. Furthermore, easily wearable, long battery life, and low cost medical care products will be available to compensate on the lack of medical care resources due to the rapidly changes of the aging of society.
